Title: Process for the recovery of tin from tin ores and other tin-bearing materials
IPC: B60P3/32
Filed: 1968-10-25
Abstract: Phosphorus, or a phosphorus-containing material, is added to a tin-bearing material, which also contains iron, in an amount of at least 0À1 gm. atom of P. per gm atom of Fe, and the tin is volatilized as tin sulphide. The phosphoruscontaining material may be any material in which phosphorus occurs in chemical combination, but is preferably a raw alkaline earth phosphate, in particular tricalcium phosphate. The atomic ratio P: Fe is preferably between 0À3:1 and 0À6:1. Carbonaceous material, such as coke or coal, may be added.

Title: Rocking-swinging window leaf
IPC: E05D15/52
Filed: 1970-11-17
Abstract: A window having a rocking-swinging leaf which can be displaced horizontally in its plane within the fixed window-casing by means of a control system and can be brought by translational motion from a so-called "rocking" position in which the leaf is opened in a bellows-type movement to a so-called "swinging" position in which the leaf is opened as a casement window. The control system comprises a rotatable operating handle which is mounted on the leaf and adapted to displace a sliding bolt which can be detachably secured to the fixed window-casing. The control system and ancillary devices for attaching the leaf to the casing are so arranged as to permit translational motion of the leaf in the plane of the casing between any one of three positions, namely the closed position, the "rocking" position and the "swinging" position. The centralized control of the leaf from a handle which is carried by this latter permits considerable simplification of the guiding means while the motion-transmission means are constituted in addition to the sliding bolt and ancillaries by the leaf itself.

Title: Method and arrangement for the continuous thermal treatment of granular material with a gas
IPC: F28F27/02
Filed: 1971-01-08
Abstract: A device for the continuous thermal treatment of a granular material by means of a gas comprises a container having an inlet for the granular material which opens into a chamber arranged above a stationary gas-permeable material support which may be in the form of an inclined perforated wall. The container includes walls around the support, one of which at least includes a material outlet, for example, which is arranged at the lower end of the support. A gas is directed upwardly against the support at a plurality of separated areas in a flow stream which is regulated to maintain the material in a homogeneous loose fluid bed above the support. Means are provided at the outlet for effecting an infinitely vertically adjustable overflow. A throttling device is arranged in the flow paths of the fluid at a location before the support in order to selectively vary the velocity of gas flowing through the support and along the feed travel of the fluid bed of granular material. In accordance with the method of the invention, the granular material is directed into the chamber above the stationary support and the overflow to the outlet is set at a predetermined level. Thereafter, a treatment gas is directed through at least two distinct paths alternately upwardly through separate divided portions of this support. The gas flow is controlled so that there is an alternate flow first to one side and then to another side of the fluid bed and thence outwardly through the outlet along with the granular material which moves over the bed level.

Title: Alternating current circuit-interrupting system comprising a rectifier shunt path
IPC: H01H9/54
Filed: 1971-01-13
Abstract: A medium- or high-voltage switching system for AC current comprising two series-connected switches substantially simultaneously opened by random operated opening means. The first switch is shunted by a series arrangement of rectifiers and of a thyristor having together a reverse voltage rated to withstand the restriking voltage across said first switch. Electronic trigger means feeded by the arcing voltage across the first switch and responsive to the current to be interrupted trigger said thyristor shortly before current zero in the appropriate half-cycle to commutate said current from the switch to the shunt path. The arcing interval of the first switch subsequentially deionizes and the opened second switch prevents application of the recovery voltage to the rectifiers.

A machine is also disclosed for loading and unloading these containers and is adapted to do so when the containers are in a stack.
Patent ES-416102-A1 (ES)
Title: Corrective heating of pneumatic tires
IPC: B29D30/06
Filed: 1973-06-20
Abstract: Adverse effects on pneumatic tire performance caused by an excessive variation in radial force are reduced by localized heat treatment of the cured pneumatic tire. The area where an excessive variation will occur is determined and the tire is suspended on a special heating fixture with its axis of rotation disposed horizontally such that said area is located vertically above the axis. Heat is applied to a portion of the inner surface of the tire adjacent said area for a predetermined time and/or until a predetermined maximum inner surface temperature is reached. This treatment results in a reduction in the magnitude of the force variation.

Patent ES-418497-A1 (ES)
Title: Temperature regulating control valve
IPC: F24F11/76
Filed: 1973-09-05
Abstract: A thermal responsive fluid control valve is provided in which the thermal responsive element forms a portion of a control bleed loop around the main valve. The pressure of the fluid itself is used to provide a motive force for positioning a piston which controls the output of the valve. The pressure on one face of the piston is controlled by the thermal responsive element, but the thermal responsive element is not used to provide a mechanical load directly to the piston and, therefore, stresses normally associated with a thermal responsive element are substantially reduced. Feedback is provided between the piston and the thermal responsive element. Pressure limiting and pressure override features are also provided on the control valve, with these features being separate from the thermal regulating feature thereby avoiding normal instability tendencies associated with combined temperature and pressure regulators.

Title: Modular integral motor controller
IPC: H01H89/06
Filed: 1976-11-10
Abstract: A motor controller providing a disconnect and a single set of movable contacts, to provide operation and protection of a motor and associated circuitry over a complete range of possible currents. Plug-in modules for a circuit disconnect, a solid state overload relay, and an instantaneous trip unit are provided. The disclosed integral modular motor controller consists of five major components: (1) an isolator switch, (2) arc chambers, (3) a linear slot motor drive, (4) a drive operator, and (5) a solid state control. For a normal motor starting operation and for fault currents up to a predetermined value, such as 1200 amperes, an electromagnetic actuator is used to open the contacts a relatively small distance such as 0.25 inch. For higher fault currents a drive or linear slot motor opens the contacts to a greater separation such as 1 inch. The disclosed modular integral motor controller utilizes a disconnecting switch connected in series with a movable bridging contact arm on which arm mounted a pair of spaced apart movable contacts aligned to engage a pair of stationary contacts when the motor controller is in the closed position to complete an electric circuit to the controlled motor. The bridging contact arm is provided with two open positions one for use in motor control and relatively low fault currents, wherein relatively small contact separation is involved, and a second open position used during high fault currents and current limiting situations, wherein the movable contacts are separated from the stationary contacts by a relatively large separation.
